Mich., a corporation of Michigan Application August 2, 7 Claims.

Our invention relates generally to printing equipment and moreparticularly to a quoin.

As set forth in the patent application to James Edgar Lee and FreemanBarney, No. 1,948,821, allowed February 27th, 1934, quoins are subjectto hard use and abuse and must be operated quickly and easily and theinstant invention not only attains the several advantages referred to inthe Lee and Barney patent but it also obtains several other advantages.

One of these advantages relates to means for locking the two slidingwedge members in their adjusted position.

Continuing, another advantage resides in means for indicating the degreeof lateral expansion of the quoin, this being necessary in order thatthe quoins may be replaced in their exact former positions. That is, theprinter is able to observe the degree of expansion of the quoin and thenunlock it whereby changes may be made and then relock it in exactly thesame position. Furthermore, the degree of expansibility may be more orless permanently indicated or written upon the quoin immediatelyadjacent to the indicia thereon as will be set forth later in thespecification.

Further advantages will become apparent to those skilled in this art asthe description proceeds.

In the drawing:-

Fig. 1 is an enlarged fragmentary view of the indicating means as placedupon the quoin.

Fig. 2 is a fragmentary view of our invention. This view shows the quoinin inverted position and with the outer wedge member removed.

Fig. 3 is a cross sectional view taken along the line 3-3 of Fig. 2.

Fig. 4 is a view taken along the line 4-4 of Fig. 2.

Like numerals refer to like parts in the several views.

Referring now to the drawing, numeral 54 indicates the channel shapedmain element having holes 55 and 56, these holes being adapted toreceive the feet 51 of a bridge element 58. This bridge element isformed of spring material and has a raised portion 59 as clearly shownin Fig. 2.

The outer wedge member is indicated by the numeral 66 and is mounted inthe channel shaped member 54 by means of the pin and slot connections61, only one being shown.

The inner wedge member 68 is cut away as indicated at 69 and is notchedas indicated at 10, these notches receiving the raised portion 1934,Serial No. 738,094 (01. 254-42) 59. is indicated by numeral II. Therotation of the key causes movement of' the inner slide 68 and thespring or bridge member 58 causes yieldable engagement between theraised portion 59 and the notches it to thus maintain the wedge membersin their-adjusted position.

It will be noted that the bridge member 58 is removably mounted in thechannel shaped member 55 and thus can be removed and replaced asdesired.

The inner wedge member 68 carries indicia, shown in dotted lines in Fig.1, and a certain one of these indicia is exposed through the opening 4|.As shown in Fig. 1, the substantially rectangular line surrounding thereference character 8 indicates the boundary of a cadmium platedsurface. This surface carries the particular pencil notation, which isindicative of therparticular indicia exposed through the hole 4!. Thispencil notation serves to temporarily record the registering number andthus the quoin can be removed and then replaced in its exact originalposition as many times as desired. The pencil mark upon the cadmiumsurface can be easily wiped away when it has served its purpose.

The operation of our device is apparent to those skilled in this art.The quoins are utilized in the usual manner and the wedge members areretained against retrograde movement and therefore the exact degree oflateral expansion of the quoin may be obtained upon reinsertion of thequoin whereby any register feature that may be in the form will bepreserved.

Having thus disclosed our invention, we desire it to be understood thatthe invention is in nowise limited to the particular illustratedembodiment disclosed, the scope thereof being set forth in the followingclaims.

We claim:

1. In combination, a channel shaped member, an outer wedge memberslidable between the flanges thereof, an inner wedge member locatedbetween the web of the channel shaped member and the outer wedge member,means for moving the wedge members relatively to each other, one of saidwedge members being cut away to form a recess between the same and thechannel shaped member and locking means located in said recess, saidlocking means engaging the channel shaped member and one of the wedgemembers for preventing undesired movement therebetween.

2. An article of manufacture of the class de- The shell which receivesthe operating key scribed comprising, a main element, wedge membersslidably mounted therein, indicia on one of the wedge members, said mainelement being cut away to expose one of the indicia and means to movethe wedge members relatively to each other whereby the indicia aresuccessively exposed, said main element being plated with cadmiumclosely adjacent the cut away portion whereby a pencil notation may betemporarily placed thereon.

3. In combination, a channel shaped member, an outside wedge memberadapted for lateral movement between the flanges of the channel member,an inside wedge member, means for moving the wedges relatively to oneanother, one of said wedges having a roughened surface thereon, a springmember having a raised portion and an opposed projection, said raisedportion frictionally engaging the roughened surface and said projectionbeing removably associated with the channel shaped member for thepurpose described.

4. A combination of elements as set forth in claim 9in which one of saidwedges has a plurality of characters thereon in longitudinally locatedrelationship, said channel shaped member having an opening therethroughto successively expose the characters.

5. A combination of elements as set forth in claim 9 inwhich one of saidwedges has a 7 member, an outer wedge laterally movable therein, aninner wedge longitudinally movable, notches on the inner wedge, saidchannel having two spaced holes, and a spring having feet located insaid spaced holes, said spring having a bridge portion spaced from thechannel member and a raised portion yieldably engaging the inner wedgeto frictionally retain the same in its adjusted position.

'7. A quoin comprising, a main element, an inner and an outer wedgemember slidably mounted thereupon, said inner wedge member being cutaway to form a recess, and locking means including a spring frictionallyengaging surfaces upon the inner wedge member and the main elementlocated within the said recess.
